What is the impact of dietary organic acids on the gut villi height and FCR of brown layers?

Organic acids are essential feed additives in modern antibiotic-free brown layer nutrition. When incorporated into the feed, these acids lower the pH of the crop and gizzard, enhancing pepsin activity and protein digestion. In the small intestine, organic acids exist in both dissociated and undissociated forms; they penetrate the cell walls of Gram-negative pathogens like Salmonella Enteritidis and E. coli, disrupting their metabolic function and causing cell death. Additionally, butyrate acts as a direct energy source for enterocytes, significantly increasing the height and density of intestinal villi. Larger villi expand the surface area available for calcium and amino acid absorption, directly leading to heavier brown eggs, stronger shells, and a 4% improvement in FCR.
